How we calculate our numbers

Across this website we use a range of statistics. The purpose of this section is to provide a more detailed explanation of what those numbers mean. 

As at 31 March 2023

£26+ billion​ of capital committed or arranged:​ Combining historic activity from 2012 to 30 September 2022 where UK Green Investment Bank (GIB), GIG or Macquarie Capital have contributed equity or debt, or arranged third-party capital and / or financing.

90+ GW in development​: The total capacity of green energy assets in development that GIG has an equity investment in or that are included in funds using the GIG brand as at 31 March 2023. The GW figure includes 100% of the potential generating capacity of each asset, not the proportion owned/managed by GIG or the funds.

Supported 5+ GW ​of renewable energy projects with PPAs​: Total capacity of renewable energy projects in development, construction or operation where GIG (either directly or via portfolio companies) has contributed equity investment, which is supported by power purchase agreements structured by GIG or its portfolio companies.

Green impact - As at 31 March 2022

212,093 ktCO2e greenhouse gas emissions avoidance: Total estimated GHG emissions avoidance over the lifetime of our investments to date. Estimated number of equivalent cars removed for 25 years, based on standardised petrol vehicle efficiency and mileage.

590,318 GWh​ renewable energy generation: Total estimated energy generation over the lifetime of our investments to date. Equivalent homes powered for 25 years, based on country specific data (Enerdata).

The latest published green impact data can be found in our Progress Reports.  GIG only reports estimated green impact for projects where GIG has provided a binding commitment to make a principal investment at, or subsequent to, the project reaching final investment decision (FID).

Further details of our methodology for calculating Green Impact are provided in our Green Impact Reporting Criteria.

Note: where reference is made to GIG these statistics include historical Macquarie Capital activity which was integrated with GIB to form GIG in 2017.
